Cooler, seasonable conditions will overspread the region in the wake of Wednesday’s cold front. That front brought isolated but much-needed rain to Eastern Massachusetts, which remains in the midst of a persistent severe drought. Locally, clear skies and high temperatures in the mid 70s will persist into the weekend before another system approaches from the west by Sunday, bringing a cold front and another opportunity for precipitation. Near the Carolina coast, minimal Tropical Storm Julia will continue to meander, bringing squally weather and heavy rain to coastal regions. Julia is forecast to remain weak and nearly stationary over the next several days before weakening and moving onshore. Elsewhere in the nation, rain and thunderstorms will overspread the Plains as a developing system organizes over the central United States and progresses quickly eastward. Otherwise, calm weather and clear skies will be the norm across much of the country as the Autumnal Equinox approaches.
After a warm day, a cold front will come through tonight, bringing some chance of rain and a cool weekend to sweep away the stress of career week. A high pressure system will come in to bring clear skies and temperatures in the mid-60°s to the Boston area for the weekend, serving as a friendly reminder that the first official day of autumn was Wednesday, September 21. The clear skies and high visibility may give everyone a reason to smile on Monday morning.
Cloudy and muggy weather should continue through Friday as a front approaches Boston from the south. Warm, tropical air is being squeezed between a low pressure system to our southwest and high pressure to the northeast. Today, the vicinity of the high pressure system will limit rain chances in Boston. As the high breaks down tomorrow, an area of rain will move in from the south, bringing moderate rainfall and patchy fog. Rain chances remain high through the weekend as the persistent low to our east makes its way toward New England. Meanwhile, the National Hurricane Center is watching a recently-developed tropical storm in the Caribbean which could potentially impact the U.S. next week. Although a tremendous amount of uncertainty remains, Tropical Storm Matthew will be closely monitored in the coming days. Several weather models show the storm trekking west before taking a sharp turn and continuing north along the east coast. Models also show the system strengthening, putting it at hurricane status in the next several days. Its implications for the east coast will be more certain by the end of the weekend.
An autumn front is poised to bring cooler temperatures and clear skies to New England this weekend. Following today’s clouds and showers, cold crisp air will be ushered into the region on strong gusting breezes from the north and northwest. The cooler weather will be accompanied by strong high pressure and light winds that could allow temperatures to drop near or into the 30s F on Friday and Saturday nights.
This week has had quite the juxtaposition of autumn leaves with temperatures up to 80°F (27°C). Hope you all got your Instagram pictures taken because these temperatures won’t be sticking around much longer! In fact, seven years ago this week, Boston had already had its first snowfall of the season. Up to four inches fell in the Boston area on October 19, 2009 resulting in unhappy Patriots fans due to a nearly snowed-out game and bemused Florida-raised college students.
The Institute’s relatively rainy autumn continues today, as a low pressure system will develop and pass from west to east over southern New England. This storm will likely bring light to moderate rain showers to the Boston area throughout this afternoon and evening. Depending on its exact track, the frontal system could also bring another spike in temperatures: areas to the south of the center of the low will see temperatures in the upper 60s, while those to the north will remain in the 50s (°F). If the storm does pass to the north, a warmer afternoon with significantly less rain is possible. This afternoon’s storm system could bring up to a half-inch of rainfall, continuing a relatively rainy trend that began around a month ago. The weather monitoring station atop the Green Building has measured 7.30 inches of rain since September 30th, compared to just 6.56 inches in the four months prior. The fall and winter months generally feature more precipitation than those in the summer, so more rainy weather will be needed to alleviate the current drought in Massachusetts. After tomorrow’s storm moves out to sea, the sun will return for the weekend. However, temperatures will be kept a few degrees below normal by a brisk northerly wind on Friday, and by the presence of an upper-level trough on Saturday and Sunday.
A cold front swept through the area on Wednesday, and it will be followed by high pressure and mostly clear skies on Thursday. The high pressure system over Montana and low pressure system over southern Hudson Bay will both shift east during Veterans Day, and the cyclonic flow from the low pressure system will bring us cold air from the northwest. This cold front is expected to pass through the area on Friday evening and give us temperatures close to freezing on Friday night, and low temperatures on Saturday. The southeastward-moving high pressure system will build up during its passage over the Great Lakes early Saturday, and the westerly flow caused by it will bring dry, warmer air into the area on Sunday. Expect mostly clear skies throughout the weekend. The dry air and clear skies are expected to persist through Tuesday. Except for Friday night and Saturday, the temperatures are normal for this time of year: climatological mean high and low temperatures are 53°F and 40°F, respectively. While we experienced more rain than usual in October, the yearly accumulation is significantly lower than climatology: 27 compared to 37 inches. This is still far from the lowest recorded precipitation accumulation at this time of year, which was 20.27 inches in 1965.
Clear skies and abundant sunshine will bring moderate temperatures and calm winds to the region through this weekend. High temperatures will remain slightly above normal in the upper 50s in advance of an incoming low pressure system from the west. That system will be this year’s first significant winter storm in the continental United States and is poised to bring heavy snowfall and possible blizzard conditions to much of the High Plains and Upper Mississippi Valley. In conjunction, a cold front will sweep across the central and eastern United States, bringing a chance of showers followed by much cooler weather to most locations.
The first flakes of snow fell over Cambridge on Sunday night, marking the unofficial start of the winter season in many people’s minds. It will not get quite cold enough for snow for Boston over Thanksgiving but parts of the midwest and northeast United States have a snowy holiday weekend ahead. In Boston, high winds from the northwest will be replaced by more docile southeastern winds at the end of the week, perhaps abating the bitterness of the dropping temperatures. Over the week, a warm front will push out the current high pressure system sitting over the northeast, bringing rain and cloudy skies.
Cool air and clear skies will follow behind the departing front that brought widespread rainfall to Boston last night. Today, cloudy skies will stick around before being pushed out by drier air this evening. The weather remains amicable this weekend, with clear skies and highs in the mid 40s°F.
An Arctic air mass will plunge into the northeastern United States this weekend, causing temperatures to plummet significantly below normal. The cold air will begin to make its way into our region tonight, as a stiff northwesterly breeze develops on the backside of a low pressure system currently passing eastward through Quebec. Cold air advection will continue through the day tomorrow, with the wintry wind transporting frigid Canadian air directly toward the Institute. By Saturday, the cold air mass will be firmly in place, causing both high and low temperatures to be around 15 degrees Fahrenheit lower than normal for this time of year.
Southwesterly flow will advect unseasonably warm air toward New England on Wednesday and Thursday. A low pressure system will pass to the west of Massachusetts on Thursday, and even though most of its associated precipitation will fall inland, there is a high chance of rain on Thursday morning and early afternoon. The winds will be strong at around 15 mph.
Across the region, relatively mild conditions will persist, with partly cloudy skies and high temperatures in the mid to upper 40s through the weekend as high pressure settles across the region. This calm period will not last long, however, as a powerful storm system is forecast to develop across the deep south over the weekend and move toward the Northeast early next week. Across the west, heavy rain and snow continue to pound the region; only 65 percent of California remains in a drought, down from 100 percent just three months ago. Incredibly, only 2 percent remains in exceptional drought, down from 21 percent and 42 percent three months and one year ago respectively.
The low pressure system which brought snow to the area earlier this week continues to move off to the northeast. Behind the system, colder air from central Canada will filter in, bringing drier conditions and mostly sunny skies to Boston. This weekend, a colder plume of Arctic air will swing through New England. As the air mass settles in, highs will sit around the freezing mark and lows should dip below 20°F (-7°C).
Today, parts of Massachusetts will likely pick up over one foot of snow as a low pressure system passes to our southeast. Accordingly, the National Weather Service has issued a Winter Storm Warning for the area until later this evening. For Boston, snowfall should increase through the morning, with the brunt of the snow occurring in the late morning and early afternoon. Most weather models have accumulated snow totals of 9-13 inches in Boston by early evening, after which snowfall begins to taper off. Snow cover, combined with colder and drier air behind the departing low, will set the stage for single digit temperatures tomorrow morning. After today’s system, Boston has a chance for lighter snowfall early Saturday morning in the form of snow showers. A third system approaches New England on Sunday, bringing another opportunity for rain and snow.
Although Monday marked the official First Day of Spring, the Northeast appears to have a different idea about what that means than the rest of us. Get all the sun you need today because this weekend is going to be perpetually overcast with some rain and snow. If you're getting out of town for the break, try to bring some spring-like weather with you when you come back! For those staying in Beantown for the week, you can expect temperatures around 40°F (5°C) during the day and relatively low wind speeds.
Cloudy skies today will lead to rain chances tomorrow as a low pressure system pushes east towards the region. Unlike other recent rain events, this system will prove too weak to displace the cool air over the region. As a result, no significant warm up will occur prior to its passage. Cool air became firmly entrenched in the Northeast over the last several days as a backdoor cold front slid inland from the coast. This airmass will persist for quite some time, since no significant system is poised to push it out anytime soon. Thus, highs in the 50s fahrenheit and lows in the 40s can be expected for the next several days as Spring’s gradual warming trend is slowly realized.
Boston has seen its fair share of rain over the last couple weeks, but some warmer and drier weather is on the way for the weekend. Today, we are between systems as a weak front approaches from the west. Friday morning, the passing front will bring a possibility of rain showers in the early afternoon and a high around 75°F (24°C). As southwesterly flow strengthens behind the front, temperatures should approach the 80°F mark by Saturday afternoon. The price we will pay for warmer weather is a chance of showers during the day, but any rain should die down by the evening. For OneWorld, expect mostly cloudy skies with temperatures in the lower 60s°F (16°C).
In this season of formals, carnivals, and other end-of-year celebrations, the weather seems to be enjoying itself by keeping us on our toes. After a clear Thursday, the clouds will come rolling in with a passing front bringing a rainy and chilly Friday. Seniors shouldn't fret, though; the rain will be long gone in time for Senior Ball on Saturday night, but the sun will still be hiding in order to give each of you your time to shine. Early next week, expect warm and sunny days with cool, partly cloudy nights.
Fans of the past week's weather will be happy to learn that similar weather is in store for the Institute for the remainder of the week. The absence of any strong weather systems will result in mostly sunny skies to begin the day, with a sea breeze and a scattering of shallow cumulus clouds developing in the afternoon. Our proximity to the Massachusetts Bay will keep temperatures from escaping the mid-50s (°F), causing high temperatures to be some 10°F cooler than normal for this time of year.
Harvey unleashed over 25 trillion gallons of water on Texas and Louisiana; to understand just how much water this is, consider that if this volume was placed on MIT’s campus, it would extend about 140 kilometers into the sky.
Irma is currently located just north of Hispaniola in the Caribbean. It is forecast to approach Florida on Sunday before making a sharp right turn to the north and potentially impacting Florida, Georgia, and/or the Carolinas.
Tranquil local weather will continue across the area as the late summer cool down slowly begins.
We have experienced unseasonably warm weather this week, and Wednesday's high of 86°F was the highest September 27 temperature ever recorded in Boston. However, the temperatures started dropping after a cold front from the northwest passed over us on Thursday. Tropical storm (formerly hurricane) Maria will be passing to our southeast during Thursday and Friday, but the storm will be too far away to affect us with any strong winds or rain. The rain that we can expect on Saturday is instead coming from the northwest, where another incoming cold front will bring along a minor low pressure system. Expect light showers on Friday night and during Saturday. After the passage of this low pressure system we can expect several days of mostly clear skies, when we will be under a large high pressure system ranging from Maine to the Carolinas in latitude and from the coast to the Great Lakes in longitude. This will likely bring temperatures around 70°F and plenty of sun during Monday through Wednesday.
A weak low pressure system is currently exiting the East Coast; in its wake, cooler, more seasonable weather and sunny skies will dominate today and Friday. This brief return to autumn will be short lived, however, as the unseasonably warm temperatures the Northeast has experienced periodically over the past month will return for the weekend. On Saturday, high temperatures will surge back into the mid-70s with a chance of rain in advance of an approaching cold front. The front should pass through the area late Sunday; in its wake, autumn-like weather will return again, with highs in the 50s and 60s and lows in the 40s for at least the greater part of next week. Although local conditions have been calm, the weather has not been so tranquil across the rest of the United States.
Is it quickly becoming the time of year when Cambridge reminds us that sweaters were originally designed for survival rather than for style. Break out your scarves, gloves, and hats, for the freezing weather has officially arrived! The weekend is shaping up to be sunny but chilly. No precipitation is forecasted for Boston for the next few days, but other regions of the United States are already seeing their first snow.
On Tuesday, don’t chicken out of going outside, since we will experience milder temperatures than the last few days have brought, with highs in the upper 50s and lows in the 40s. Wednesday morning and midday bring a chance of preci-pie-tation, before the rain quits cold-turkey by Wednesday evening. From Thanksgiving Day through the weekend, we will experience colder temperatures with highs in the 40s and lows in the 30s, with the brief exception of slightly warmer weather on Saturday. If you’re planning on camping out in mall parking lots the night before Black Friday, beware of chilly weather in the Northeast, although it should be above freezing elsewhere. Looking to the rest of the United States, there is a chance of rain in Florida on Thursday, and the upper Rockies will continue to experience their usual acc-yam-ulation of snow. In the Northwest, we can expect rain over the entire forecasting period - and more than a poultry amount; expect quite the dreary weather. So if you’ve de-cider-ed to fly home from Oregon or Washington on Sunday, keep an eye out for continuing rains. This weekend is a good time to appreciate - or lament - your hometown weather, because in Cambridge it only gets colder from here, good gravy!
Following yesterday’s brief excursion around 60°F, a weak cold front continues to progress eastward across the Northeast and will move offshore early tomorrow. In its wake, we will experience more seasonable weather with highs in the 40s, lows in the 30s, and no precipitation over the weekend and early into next week. No major weather systems are expected to impact the US before perhaps the middle of next week so enjoy the calm weather and cool, sunny start to December!
While Thursday and Friday promise to be pleasant and sunny, there is a chance that we could experience snow or rain during the weekend. The large scale flow over New England will be southwesterly over the coming days, and Boston will be on the edge between the cold inland air and the warmer ocean air during the weekend. The precipitation will occur in this transition region, and whether or not we get snow and/or rain will depend on which side we end up on. One extreme is cold temperatures (low 30s) and clear skies, while the other is warm temperatures (high 40s) and lots of precipitation. We will most likely end up somewhere between the two, with temperatures around 40°F and intermittent rain during the day or snow during the evening.
By the calendar, we are now several days into astronomical spring. By the frigid weather, however, you’d never know it. The 4th nor'easter in the past 3 weeks is currently pulling away from the Eastern US coast, has brought heavy snow to much of the mid-Atlantic and Northeast. In its wake, atypically cold temperatures will persist, with high temperatures in the lower 40s °F and low temperatures in the 20s. The cold, winter-like weather that has dominated this month shows no signs of leaving anytime soon either. March is on pace to be colder (and snowier) than February, with a mean temperature so far of 35.6 °F (2.0 °C) compared to February’s warmest ever 38.1 °F (3.4°C). March was also warmer than February last year, but this feat had only occurred twice before in the 144-year meteorological record at Boston and is extremely rare for the Eastern US. Nevertheless, it is almost April. Spring is here - the days are getting longer, the sunshine stronger, and there’s only so long Old Man Winter can maintain an icy grip on the region.
The hot, scattered rainstorms that characterized this past week are set to continue. The past week brought heavy rain and thunder most days, creating a danger of flash floods. In the next few days, watch for more flash flood warnings due to heavy thunderstorms, at least until Sunday. After a summer of relatively light rain, this week reminds us that we live in New England. However, New England isn’t the only region to have heavy rains this past week. The same rain that hit Boston traveled up the eastern coast of the U.S., ruining beach trips everywhere. In Colorado, heavy rain and hail caused flooding and much hail damage in the mountain west. It's been a wet week.
The weather today will be good for Career Fair activities as a seasonable but breezy and humid air mass overspreads the area in advance of a strong cold front Friday night.
Boston doubled its snowfall total for the season this past Tuesday, as a brief snowstorm brought the city's snowfall total to 4.7 in (12 cm), the third lowest seasonal total to date on record.
The National Weather Service Climate Prediction Center is predicting a colder-than-normal month ahead, with the cold starting this weekend. After the snow last night, another low pressure system is expected to hit the Northeast this weekend, potentially bringing in more snow and rain on Saturday night.
We are now deep into January and the greater Boston area has been cold and sadly snowless for the most part. There have been possibilities of light snow showers the past week and into the next, but nothing heavy enough to last and thoroughly enjoy. Friday night will bring in a cold front and blustery (a fun word for breezy!) weekend conditions. Although the outdoors has hardly been a winter wonderland, in western Massachusetts, the weather has been warm enough to go outside and take some long hikes in the fresh air.
Unfortunately, the weekend we will experience a 20 degree drop as Pi Day approaches. Despite the gloomier temperature on Sunday, don’t forget to celebrate Pi Day!
Although the weather here in Boston will bless us today with one more day of sunshine and ridiculously high temperatures, don’t expect it to last. Temperatures will start heading down towards the weekend and into next week, with showers Friday morning and Sunday afternoon. So, instead of waiting for your day off to go out... is taking that midterm outdoors really such a bad idea?
We finish the month with uncertainty as a set of warm and cold fronts drift over the region. There could be periods of rain or showers throughout the next two days, but even our local NWS forecasting office is uncertain of when or how much rain will arrive.
